Some wiki URL can't read by fopen() in PHP.

Some wiki URL can't read by fopen() in PHP.

■How to do it well ?

Use "ini_set('user_agent', '...');" just before "fopen()".


■Problem


    On "Foreign Mom Next for iPad iPhone PC"(http://www.mylovewill.com/eng/index.php?LANG=en) ,
    translate "http://simple.wikipedia.org/wiki/Mathematics"
    and click the link, "Fermat's_last_theorem".
  
    It shows an ERROR.
    "Warning: fopen(http://simple.wikipedia.org/wiki/Fermat%27s_last_theorem)
    [function.fopen]: failed to open stream: HTTP request failed!
    HTTP/1.0 403 Forbidden in /home2/mylovewi/public_html/eng/eng.php on line 152"

    But, the link, "Pythagorean theorem", goes well.


■Investigation

    Thinking the special character, ('), is the reason.
    I tried URLdecode() URLencode() functions, but, I was not able to be improved.
  
    I made test program A for investigation with the other server.
    I tested and analyzed packets by tcpdump.

■test program A

# cat test.php
<?php
$f = fopen("http://simple.wikipedia.org/wiki/Fermat%27s_last_theorem", rb);
if($f){
        while(!feof($f)){
                echo fread($f, 8192);
        }
        fclose($f);
}
?>
#

■log by tcpdump

# tcpdump -X -s 1600 port http

■Log analysis and measures plan

    http request are two packets, timestump ,
    17:57:33.446444 17:57:33.528373.
  
    In fopen(), there are only GET and Host:.
    And the response status is "HTTP/1.0.403 Forbidden".
    More the response bosy is
     "Scripts should use an informative User-Agent string with
      contact information, or they may be IP-blocked without notice".
  
    I made test program B for investigation.
    It goes well.

■test program B

Foreign Mom Next for iPad iPhone PC

"Foreign to Native for iPad iPhone" was changed it's name.


New name is ...



Foreign Mom Next for iPad iPhone PC



Immediately, go to the tool

Tool for a person who wants to get the high foreign language skill

This is a tool to get the higher foreign language skill.

foreign language skill = reading + listening + writing + speaking

And vocabulary is necessary for reading skill.

This was developed as a tool for vocabulary.

A tool for busy people

For a busy person, it is very important to learn a foreign language effictively.

A busy person is :
  • He do not have time to read a boring textbook.
  • He do not have time to make a vocabulary notebook by a dictionary.
  • It is necessary for him to master the vocabulary of the specialized field, quickly and effectively.

This was developed for a busy person reading and understanding foreign language and memorizing words.

Do you want to increase foreign vocabulary effectively?


The traditional method to gain the vocabulary of the foreign language is this :
  • Read a foreign language every day
  • Examine an unknown word in a dictionary
  • Transfer the word examined to a vocabulary notebook
  • Review a vocabulary notebook every day
They said "There is no royal road to learning."

By the traditional method, it took many trouble and many time.

WorkThe time requiredHardship degree
Read a foreign language every daysmallmiddle
Examine an unknown word in a dictionarymanymany
Transfer the word examined to a vocabulary notebookmanymany
Review a vocabulary notebook every daysmallmiddle

The speed to read the foreign sentence becomes extremely slow when you took the traditional method.
Because the word that you do not know comes out and comes out and comes..., it becomes slow.

As unknown words increase, you do not understand contents and feel boredom.

And the traditional method demands you a desk and a chair.
Do you want to make yourself at home in a sofa and a bed and to read a foreign language ?

Do you want to write it to the vocabulary notebook in a pure character?

To review a vocabulary notebook is not pleasant.
Strong-willed will is necessary to carry it out.

Many people are exhausted and fail on the traditional method after all.

Will there be the solution as expected?

Will there be the solution as expected?

All of you have a question from me before suggesting a solution.
Have you ever been read a picture book by your mother in small childhood?

Please remember a state at that time.

When the words that you do not know came out, you ask a mother.
"Mom, what's that?"
Your mother gives you an answer easily.
"Well, that's ...."
And Your mother read the point of the book to your interest.

On the next day, your mother asked you a question.
"Baby, do you remember the story read yesterday?"
"Mom, I do. That's fun."
Your mother said,
"You're good baby. And ..."
You said,
"Well, that's ...."
Your mother said,
"Great! I will read a picture book today."
...

Your mother taught you words affectionately.

As one of the methods to gain vocabulary effectively, please examine Foreign Mom Next.

You please read a foreign language site with this.
Please touch the word that does not understand the meaning, the meaning does popup.
This automatically records a word and a meaning to a vocabulary notebook.

When you review a vocabulary notebook, this makes a quiz from your favorite range.

Here, I will explain the quality of translation honestly.

There is a simple one translation for the word.
Translation of the sentence of the grandmother cannot be called the perfection.

But you can correct the contents of the vocabulary notebook,
this will reply you by new corrected contents about the same word.
